Channel 2's Michael Seiden was in Peachtree City, where residents are cleaning up after floodwaters rushed into their homes.

Amy Byars said her neighborhood on Lake Peachtree looked like it was part of the lake Saturday morning.

"You could've ridden a boat through there," Byars told Seiden. "Some of these lower-lying houses, you would have thought they were in the lake, too. There were ducks in their yards. We got to higher ground because I wasn't going to risk my life."

Walls said that the Tinsley Mill Village neighborhood got more than half a foot of rain in the last 24 hours.

"It came down like crazy!" Alex Isbell said. "Like real quick. A lot of thunder and lightning."

The flooding caused hazardous road conditions in Fayette County.

"I run heavy equipment for a living, and I'll be the first one to tell you, 'Do not get into something if you can't see the bottom of it.' It's not worth it," Isbell said.

The waters had mostly receded by Saturday night.

Luckily, no one was injured and most homeowners said they have flood insurance.
